Example of evolutionary tracks for a pair of stellar models fulfilling the constraints explained in the text, and with Y = 0.27, Z = 0.016 and αOV = 0.2. For this particular pair Teff,1 = 6860 K and Teff,2 = 6680 K, the requested difference in radius with similar masses is fulfilled thanks to a more evolved stage of the primary component.
